An optional page shows calculations for the Dräger Dolphin Semi-Closed Rebreather, including 'gas time' left in tank, fraction of inspired Oxygen from counter-lung, with the MOD, CoD, EAD and NDL dive parameters calculated based on the fraction of inspired O2. Be sure to check the settings for tank volumes and pressures before using the Dolphin mode, or your 'gas time' figures will be inaccurate.

I hope you find this app useful. This latest (and final) version of Nitrox Calculator is now Ad free - think of it as my gift to the diving community.

New for Version 2 - On-screen buttons to re-use calculated depth, NDL time and best mix figures, and automatically re-calculate other parameters. Also, all main Nitrox parameters are shown on one screen.

Version 2.02 - Updated with On-Screen Settings for latest O/S. Now AD FREE. But the app will no longer be updated or maintained.

Love the app except it seems to be metric only. Is there an option for ft?
